ASH-SIEVE.

SPECIFICATION forming part of Letters Patent No. 556,347', dated March1*?, 1896.

l Application filed October 25, 1895. Serial No. 566,840. (No model.)

T0 all whom t may concern:

Be it known that I, LEWIS R. HALL, of Medford, Middlesex county,Massachusetts, have invented an Improved Ash-Sieve, of which thefollowing is a full, clear, and exact description, reference being hadto the accompanying drawings, making part of this speciiication, inwhich- Figure lis a perspective view of an ash sieve or sifterconstructed in accordance with my invention and adapted for use upon abarrel. Fig. 2 is a central vertical section taken in the direction ofthe length of the shakin g-rod; Fig. 3, a central vertical section inthe direction of the line a; so of Fig. 2. Fig. 4 is a horizontalsection in the direction of the line y y of Fig. 3; Fig. 5, a detail,enlarged, to be referred to.

This invention belongs to that class of ashsifters designed for use indwelling-houses, schools, publie buildings, dac., for separating coalfrom the ashes after having passed through the re; and my presentinvention consists in a pair of oppositely-located sieves pivoted attheir upper ends within a casing and having Atheir lower ends looselyconnected by an interposed third sieve, the said sieves being vibratedby a handle or shaker which projects out through the side of the casingand the ashes escaping through its open bottom into an ash-receiverthereunder, the good coal being directed from the sieves out through anopening in the side of the casing into any receptacle provided therefor,my improved sifter being adapted for ready application or attached tothe head or cover of a barrel or other ash-receiver, and being hin gedthereto to admit of the sifter being tipped forward to facilitate thedischarge of the separated coal.

My invention also consists in certain details of construction to behereinafter described and claimed.

In the said drawings, A represents a square casing hinged at a to thetop of a barrel-cover D; Z), the lid of the casing hinged thereto at S;c, an opening in the bottom of the casing in line with an opening d inthe cover B; O', the ash-receiving barrel thereunder.

e is a side opening controlled by a metal slide 7i, which may be movedup and down in grooves t' to open and close the space bounded by theopening e, said slide having its top bent outwardly and extending upabove the top of the body of the casing, and the lid b is cut away, soas not to interfere with the movement of the slide either when the lidis being thrown up to open or down to close the easing. (See Fig. 5.)

C D are two screens of woven-wire netting located within the easingopposite to each other, the upper end of each being loosely pivoted to asupporting-rod Z, extending between the opposite sides of the casing,being attached to its rod by a couple of rings m, which permits thescreen to have a transverse play thereon. These screens C D preferablyincline downward and inward toward each other, being nearer together attheir lower ends than at their points of suspension. (See Fig. 2.)

G is a third screen located preferably in a horizontal plane andinterposed between and loosely pivoted to the lower ends of the screensC D.

Extending under the lower screen, G, is a long rod or shaker fn, itsinner end being secured to said screen, while its outer end projectsthrough a slot p in the casing and terminates in a looped handle r, andfrom the foregoing construction it will be understoodthat the mixedashes and coal to be separated are forcibly agitated by the vibration ofthe screens C D G, upon and against which they are dumped, the resultbeing that the ashes fall into the receiver C thereunder and only theseparated coal remains upon or against the screens. After the slide 71,'is raised and the casing tipped forward on its hinges (see Fig. 1) thecoal is readily discharged through the opening e into any convenientreceptacle, being guided in its exit by a short chute s and flexibleconductor t.

During the operation of vibrating the screens to separate the coal andashes from each other the casing is tightly closed by its lid b, therebypreventing the escape of any dust therefrom, said lid being of lesswidth than that of the top of the easing and abutting against the innersurface of the projecting top of the slide when down.

l. An ash-sifter-eonsisting essentially of a casing A having an openbottom c, a side IOO opening e and a. slide 7L controlling the latter,in combination With t pair of screens C D oppositely located and pivotedat their upper ends Within the easing-Pt screen G interposed 5 betweenand loosely connected With the lower ends of the screens C D sind tmeans of agitating the screens,- substfintially as described. 2. Acasing A having an open bottom c, :L side opening,r e, i slide h forclosing the latter, L conductor and a shaker n, in combination with thescreens C D G, those C D being oppositely disposed to ca-cll other andsuspended at their upper ends Within said casing, and the screen Ginterposed between and loosely connected with their lower ends,silbstmitin-lly as specified.

lVitness my hand this 8th day of October, 1895.
